When pregnant at 28 to 32 weeks, doctors will recommend that expectant mothers do a fetal growth ultrasound, and some expectant mothers also call this test small pai teratology. Today I will talk in detail about what kind of examination is a small row of dysplasia.
Fetal growth ultrasound mainly examines the baby's development, focusing on whether the size of the baby is consistent with the gestational age; measuring the amount of amniotic fluid, placenta position, etc., the doctor will use ultrasound to roughly assess the size of the baby, usually the baby size and the corresponding gestational age of the reference size difference within a week Even if the normal development difference is more than one week, the doctor will verify the gestational week according to the previous menstrual situation and the previous examination results. When the difference is more than three weeks, it is usually necessary to find the cause. Your doctor will keep an eye on your weight gain and blood sugar, and may need regular ultrasound checkups if necessary.
In addition, the doctor will also observe and assess whether the baby's important organ structure is normal, such as the heart is more than the lateral ventricles, spinal cord cones, etc. I would like to draw your attention to the fact that some expectant mothers' ultrasound reports will indicate that the baby's femur and humerus are significantly shorter than the corresponding gestational age standard. Don't panic, this doesn't have to be a real problem. On the one hand, this value is related to the reference frame chosen by the doctor, for example, the default reference frame of many ultrasound machines is based on the statistics of the European and American population, which is different from us Asians themselves. On the other hand, if the parents, especially the mother-to-be, are short, usually the degree of the baby's femur may also be affected, unless it is particularly short, such as less than four weeks, and there is a bending deformation, etc., otherwise the possibility of the baby's bone deformity is generally not large. Just follow the doctor's advice and review it on time. Examination may also detect placental maturity.
Some expectant mothers are very worried when they see the second and third levels, and think that the placenta is aging. I would like to remind you that you do not need to pay too much attention to this data, and if you are still not at ease, you can check the introduction of placental maturity and other related issues in the previous article.
Some expectant mothers are worried that ultrasound tests have radiation and are harmful to their babies, so you can rest assured. Ultrasound has no harmful ionizing radiation, and there is currently no evidence that clinically used ultrasound can endanger the safety of the fetus and the mother-to-be. and the fetal structure mentioned in the previous article. Like ultrasound, fetal growth ultrasound is not something that every expectant mother must do. This test is still necessary if you have a high abdominal circumference or weight gain that is too fast or too slow, or if you have people who have a combination of risk factors such as gestational diabetes, hypertension, or fetal movement abnormalities. Of course, the final decision you can still consult a doctor to make.
Make a judgment that suits you. At this stage, expectant mothers are also very concerned about the weight change of the baby, worried that the baby will be too heavy in the future and it will be difficult to have a smooth birth. Since the popularity of ultrasound, ultrasound weight estimation seems to have become a topic of conversation for expectant mothers. So how is ultrasound weight valued? Is it true?
First of all, ultrasound is unable to directly measure the weight of the fetus, ultrasound is to measure the fetal head data, such as head circumference, double top diameter, abdominal circumference, and long bone length. That is what we call the formula for the length of the femur, estimating the weight of the fetus. Some expectant mothers may also see that there are many online calculators on the Internet that input this data to get a baby's weight. Is this valuation accurate? Of course not. In this weight assessment formula, the baby's abdominal circumference occupies the most important factor, that is, the fat belly of the fat person. But this formula does not take into account factors such as sex, subcutaneous fat distribution, etc.
Therefore, many mothers exclaim after giving birth to the baby, and the ultrasound doctor estimates inaccurately. This is really unjust, and the pain is more to help the doctor screen the baby that is too large and too small to ensure the safety of delivery, rather than really telling you how heavy the baby is.
Well, today's article is shared here, I hope that we can have the opportunity to become a better self because of the arrival of our children, be better parents, learn to think, learn to judge, learn to analyze, and accompany our children to grow up with him.
